2 Claims. 1

This invention relates to terminal connections and more particularly to an auto-battery terminal connection, and has for one of its objects the production of a simple and efficient connection which may be easily and quickly attached to and detached from the post of a battery without the use of bolts, nuts, and the like.

A further object of this invention is the production of a battery terminal connection which is inexpensive in construction and simple in operation.

Other objects and advantages of the present invention will appear throughout the following specification and claims.

In the drawing:

Figure 1 is a top plan view of the auto-battery terminal connection, attached to a battery post;

Figure 2 is a side elevational view;

Figure 3 is a front end view of the terminal connection;

Figure 4 is a front end view of the terminal connection with the spring clamping pin removed;

Figure 5 is a side elevational view of the spring clamping pin;

Figure 6 is a top plan view of the pin;

Figure 7 is a top plan view of a modified form of spring clamping pin.

By referring to the drawing, it will be seen that IE! designates the battery which carries the conventional post II. The improved terminal connection !2 is carried by one end of the conduit !3. The connection I2 is provided with a flared portion l4 near its outer end, the terminus 15 of which is rounded, as shown in Figures l, 3 and 4.

A notch I8 is formed in one side of the connection l2 and extends from the forward end or terminus E5 to the abutment shoulder H, which shoulder is located rearwardly of the post II. The shoulder H is provided with a pair of vertically aligned sockets l8 to one side of the vertical center of the post H. The terminus I 5 is inset relative to the open side of the notch IS.

A clamping spring pin IQ of a cotter pin type having parallel legs 20 is secured to the connection E2. The parallel legs 29 fit into the sockets l3 and the legs Z'il of the pin [9 are bulged laterally, as at 2!, to conform to the contour of the transverse area of the post I I. These legs 23 terminate at their forward outer ends in a turned loop 22 which extends outwardly in longitudinal alignment with the legs 20. The loop 22 extends forwardly within the forward end of the notch F6 in a position where the loop 22 may be gripped by a suitable tool for extracting.

When placing the terminal connection l2 over a battery post, the operator will pry the spring 19 outwardly by placing a screw driver or other means between the loop 22 and the terminus IE to obtain the proper leverage to move the spring [9 laterally of the post I I or the aperture through which the post is adapted to pass. The terminal is then dropped down over the post and when the spring I9 is released the spring will then tightly bind against the post H, thereby holding the terminal l2 tightly upon the post H.

In Figure '7, there is illustrated amodified form of the pin wherein the bulged portion Zi thereof is provided with a plurality of kinked or corrugated portions 2'3 for providing a plurality of post-engaging knobs for engaging the exterior of the post ll to efliciently lock the connection in engagment with the post upon which the connection is secured.

It should be understood that certain detail changes in the construction of the terminal connection may be employed without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claims.

Having described the invention, what is claimed 1. A battery terminal connection comprising a terminal member adapted to fit over a battery post, said member having a notch along one side thereof, the terminal member having a wall at the inner end of the notch, a spring clamping pin having a pair of parallel legs, said wall having vertically aligned sockets to receive said pin, said pin being bulged intermediate its ends to provide a spring gripping means conforming to the transverse contour of a conventional battery post for clamping the member upon the post, a projecting end carried by the pin and extending longitudinally of the outer end of said slot, the legs of the pin being joined together at the projecting end of the pin, said pin normally lying wholly within and extending longitudinally of said notch, said projecting end providing means engageable by a tool for flexing the pin laterally of said notch to facilitate the placing of said terminal member over the battery post, and said spring being adapted to automatically grip the battery post when released to tightly hold the terminal member upon the post.

2. A battery terminal connection comprising a terminal member adapted to fit over a battery post, said member having a notch along one side thereof, the terminal member having a wall at the inner end of the notch, a spring clamping pin, said wall having a socket to receive said pin, said pin being bulged intermediate its ends to provide a spring gripping means conforming to the transverse contour of a conventional battery post for clamping the member upon the post, and a projecting end carried by the pin and extending longitudinally of the outer end of said slot to facilitate the insertion and removal of said pin and to provide means engageable by a tool to flex the pin laterally out of alignment with the battery post, the bulged portion of said pin being corrugated throughout the length of the 4 bulged portion and the corrugations extending transversely of the bulged portion to provide a plurality of post-engaging portions.
